ISS Daily Summary Report – 2/04/2021


FLARE (Solid Combustion Assembly): The crew removed and replaced the FLARE-Solid Combustion Experiment Module (SCEM) Igniter for Experiment Insert #2. Fundamental Research on International Standard of Fire Safety in Space – Base for Safety of Future Manned Missions (FLARE), a Japan Aerospace Exploration Agency (JAXA) investigation, explores the flammability of materials in microgravity. Various solid fuels are burned under different conditions and observed inside a flow tunnel. Microgravity significantly affects combustion phenomena and results are expected to contribute to the improvement of fire safety in space.

CBEF-L (Cell Biology Experiment Facility-L): The crew installed the Micro-G Sample Tray into the CBEF-L Facility. CBEF-L is a Japan Aerospace Exploration Agency (JAXA) new subrack facility, which is an upgraded facility of the original Cell Biology Experiment Facility (CBEF) currently aboard the International Space Station (ISS). CBEF-L provides new capabilities with additional new resources such as Full High Definition video interface, Ethernet, 24 VDC power supply, and a larger diameter centrifugal test environment. By using the original CBEF and CBEF-L as one facility for the same experiment, the payload user is provided with an upgraded experimental environment that can handle the processing of more experimental samples for a wider array of experiments.

Capillary Structures: The crew performed a demonstration of fluid flow through four parallel open capillary conduits (wedges). This completes the last session of this experiment ending a five year study. Current life-support systems on the ISS require special equipment to separate liquids and gases, including rotating or moving devices that could cause contamination if they break or fail. The Capillary Structures for Exploration Life Support (Capillary Structures) investigation studies a new method using structures of specific shapes to manage fluid and gas mixtures. The investigation studies water recycling and carbon dioxide removal, benefiting future efforts to design lightweight, more reliable life support systems for future space missions.

Astrobee: The crew installed the Perching Arms (2) hardware onto Free Flyer units and performed checkout maneuvers. Astrobee is made up of three free-flying, cube-shaped robots which are designed to help scientists and engineers develop and test technologies for use in microgravity to assist astronauts with routine chores, and give ground controllers additional eyes and ears on the space station. The autonomous robots, powered by fans and vision-based navigation, perform crew monitoring, sampling, logistics management, and accommodate up to three investigations.

AstroRad Vest: A crewmember donned the AstroRad Vest for an overnight sleep test. The AstroRad vest is a personal protective equipment (PPE) device which functions as a radiation shield for astronauts. The AstroRad shields astronauts from space-borne ionizing radiation in an efficient way, provides operational simplification, and allows for the use of recycled material on-board the vehicle. The concept behind the AstroRad evolved from a commercially available device, the 360 Gamma shield, made by StemRad Ltd., which is an effective wearable shield for first responders to radiation incidents on the Earth.

NanoRacks Platforms: The crew relocated NanoRacks Platforms 2 & 3 into Express Rack 3 in order to make room for the Spaceborne Computer hardware which will arrive on NG-15. NanoRacks Platforms is a multipurpose research facility on board the International Space Station (ISS). NanoRacks Platforms supports NanoRacks Modules in the CubeSat form factor by providing power and data transfer capabilities to operate investigations in microgravity.


NanoRacks Airlock (NRAL) Pressurization and Leak Check – Yesterday, the Pressure Management Device (PMD) was used to pressurize NRAL to approximately 5 psi to begin a 44-hour leak check. It is scheduled to conclude on Friday. PMD went Loss of Comm overnight, however, this does not have impacts to the leak check. Pressure insight was regained this morning. Ground teams are meeting today to assess the data and verify that the pressure remains within the leak check criteria. 

Regenerative Environmental Control and Life Support System (ECLSS) Recycle Tank Drain/Fill: Today the crew set up the recycle tank to drain to a ЕДВ-У. Following the setup the ground performed the tank drain using the Urine Transfer System (UTS). Once the ground specialists completed the transfer, the crew verified the recycle tank was empty, terminated the drain, and repositioned the fill/drain valve to fill.

Crew On-Board Training (OBT) Review: The crew reviewed procedures for emergency situations, such as Crew Dragon free flight Depress response, free flight fire response, and contingency deorbit, entry, and landing response. They also practiced emergency mask don/purge techniques using training only emergency masks. This is done as a refresher for the crew in the event of an emergency.
